This is U9 on a vizio main board.
K117S15
pin 1: 0.04V
pin 2: 1.53V
pin 3: 3.32V
Does that seem bad?

Re: Voltage regulator values? K117S15
15 suffix indicates 1.5V, it is working.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

3+1 Voltage Regulator for IMVP-7/VR12 CPUs
Compliant with IMVP-7/VR12, the ISL95831 provides a complete solution for microprocessor and graphic processor
core power supply. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be
configured as 3-, 2- or 1-phase VR while the second output is 1- phase VR, providing maximum flexibility. The two VRs share the
serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two chip approach.

hello ,for diy voltage injector for short killer/finder -- is it possible to use something like this - LM317 DC Linear Regulator, DC-DC 4.5~40V Turn 1.2~37V, Step Down Power Module, Adjustable
and ampere controller along (to make it zero amps ) with some addons(transistors diodes etc.) for it -- and use some 5v adaptor or 3.3v volt rail of my smps power supply as input and finally get 1v and zero amps for injecting voltage to find out short circuit component ? ..
for source input -- can we use 3.3 -4 volt 18550 battery ?( i have some of those ) and then adding ampere regulator... -
This Concept 2 rower pm5 monitor doesn't shut down. It keeps turning on and stays on after being turned off. I read on another forum by another user that replaced the same component to check the voltage regulator.
The monitor should pull around 35mA when turned on and in shutdown it should drops to around 0.060mA. Any advice on finding the voltage regulator on this board to check if it needs to be replaced?

Hello all. Excellent forum you have here - it has already been a great help to me. I am posting the details of my situation before I go and start buying parts to see what suggestions the great minds here may have on diagnostics or otherwise.
I have an Acer AL1916W monitor which has recently failed in the following way: the screen comes on at power on, but after a couple seconds the screen goes black. Using a flashlight, I can easily verify the LCD is fine but there is simply no backlight.
The power supply board is of the type ILPI-025 Rev C (Date of manufacture was... -
The ram regulator produces VTT voltage of 0.65V and the display comes. When we restart the laptop the VTT voltage becomes 0.75 and no display.[Used same ddr3l ram].
Also, it becomes 1.35 V on the ram coil and all are okay but after restarting Voltage becomes 1.5V with no display.
